BALL-BEARING.

Specification of Letters Patent.

Application filed October 19, 1907.

Patented Nov. 15, 1910'.

Serial No. 398,181.

To all 'whom 't 'may concern.'

Be it known that I, HENRY Huss, a citizen of the United States, residing at lVawa, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Ball-Bearings, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to ball bearings, and more particularly to that class thereof wherein the balls are separated one from another by interposed elastic separat-ors,-tl1is class of bearing being ordinarily termed the silent type. As frequently employed, such separators are cylindrical in form and bear at their ends against the balls, and it sometimes happens, due to the presence of grit, acid, or other obstruction, or because of some accidental occurrence in the operation, that these cylindrical separators are tilted from their normal position to such an extent that their ends are drawn under the balls. The results of this abnormal condition are not only serious to the separators themselves but also occasionally result in the destruction of the bearing. To obviate this objection I propose to employ a separator of spherical form which will always present the same configuration to the other parts of the bearing even though its position be constantly changed therein. I also propose to make the separator elastic, not only to insure its proper relation to the balls, but also to permit its partial deformation and compression, so that it may be introduced into the annular race without the use of filling openings and the like, as sometimes employed in the art. Inorder to secure these advantages and at the same time obtain a separator of the requisite durability and with sul'licient elasticity to give it the desired functions, I have hereinl shown/ang, described a spherical separator consisting of a rigid interior core and an elastic cover connected thereto. l

Referring to the drawing: Figure l is atransverse section of a bearing `with my invention applied thereto; Fig. 2 is a transverse section of the same, the section being taken at right angles to that of Fig. l; Fig.

3 is a sectional view of the separator; Fig. 4 is a sectional view of one of its outer parts or elements; Fig. 5 is a perspective view of the inner core; and Fig. 6 is a perspective view of one of the outer parts or elements.

The bearing consists of the inner ring A, the outer ring B, wherein are formed respectively the groo'ves a and Z1 that constitute the annular race, and of the balls C, C between which are interposed the separators D, D.

Each separator D is of spherical form and comprises a rigid or solid core d and an eX- ternal elastic covering d1. For purposes of convenience, this outer and elastic skin may be made in segmental sections, four such sections being illustrated, in order to facilitate its manufacture, as well as to permit its easy attachment to the core. Each section is provided with edges or flanges d3, cl3, which enter and engage corresponding slots or grooves d4, d4, in the core d,

whereby the parts are connected; and each section is further formed with 'projecting sides or crimps d2, cl2, so that when the various elements are pressed home against the against the crimps of the adjacent section, and t-hus secure their correct position as well as substantial and continuous sphericity for the entire outer surface.

make theouter sections of thin sheet-metal, but'I Vdo not desire to limit myself in this of construction and arrangement, which have been shown merely by way of example. It is obvious that the details may be varied in many ways without departing from the spirit of my invention.

What I claim and-desire to secure by Letters-Patent of the United States is as follows:

l. In a ball bearing, the combination of the casing members formed with tracks or `ways:and substantially inelastic andrv nondeformable load-bearing balls located there- Y in, together with elastic and deformable spherical separators interposed between the load-bearing balls. the said separators being capable of introduction into and removal For the purposes mentioned I prefer toP regard, nor as to the other specific features.
